Apple has begun an attack on App Store piracy. The popular resource for cracked iOS apps known as Apptrackr recently said that Apple has begun sending large amounts of takedown notices, thereby forcing Apptrackr to relocate many of its servers and implement more steps for its users to avoid legal ramifications.

In a note to users of Installous, a Cydia app for downloading and installing pirated apps from the App Store, Apptrackr frontman “dissident” explains Apple’s attempts at crippling the piracy service and how Apptrackr supporters can help keep the resource running.
